Grilling tuna steaks on a griddle is a fantastic way to achieve a restaurant-quality meal at home. The intense, even heat of the griddle sears the outside of the tuna, creating a delicious crust while keeping the inside perfectly tender and moist. This guide will walk you through every step, from selecting the best tuna to serving up a masterpiece.
Choosing the Right Tuna
The success of your griddled tuna steaks starts with selecting the right fish. Freshness is paramount. You want tuna that has been handled with care and is of the highest quality.
Identifying Fresh Tuna
Look for tuna steaks that are vibrant in color. The color will vary depending on the type of tuna, but it should be consistent throughout the steak. For example, ahi tuna should be a deep, reddish-pink. Avoid steaks that are dull, brown, or have any signs of discoloration.
Fresh tuna should have a clean, slightly salty smell. If it smells overly fishy or ammonia-like, it’s not fresh.
The texture of the tuna should be firm and springy. Press gently on the steak; it should bounce back readily. Avoid tuna that feels soft, mushy, or slimy.
Types of Tuna Suitable for Grilling
Several types of tuna are excellent for grilling. Ahi tuna, also known as yellowfin, is a popular choice due to its rich flavor and firm texture. Bigeye tuna is another excellent option, offering a similar flavor profile. Bluefin tuna is considered the highest quality, but it’s also the most expensive and should be sourced responsibly. Albacore tuna is lighter in color and flavor, and while it can be grilled, it’s best cooked slightly more to prevent it from being too dry.
Regardless of the type you choose, ensure you’re buying sushi-grade tuna if you plan to serve it rare or seared. This designation indicates the tuna has been handled in a way that minimizes the risk of bacteria.
Preparing the Tuna Steaks
Proper preparation is key to ensuring your tuna steaks cook evenly and taste their best.
Thawing Frozen Tuna
If you’re using frozen tuna, thaw it properly. The best method is to thaw it slowly in the refrigerator overnight. This allows the tuna to thaw evenly and retain its moisture. Avoid thawing tuna at room temperature, as this can encourage bacterial growth. You can also use the cold-water method: Place the vacuum-sealed tuna in a bowl of cold water, changing the water every 30 minutes until thawed.
Trimming and Shaping
Once the tuna is thawed, pat it dry with paper towels. This helps to create a better sear on the griddle. Inspect the steaks for any tough connective tissue or sinew and trim it away. This will improve the texture of the cooked tuna.
You can optionally shape the tuna steaks into a more uniform thickness. This ensures even cooking. Gently press down on the thicker parts of the steak to even them out. Be careful not to tear the fish.
Prepping the Marinade or Dry Rub
While tuna is delicious on its own, a marinade or dry rub can enhance its flavor.
For a simple marinade, combine olive oil, soy sauce, lemon juice, minced garlic, and black pepper. Marinate the tuna steaks for at least 30 minutes, but no more than an hour, in the refrigerator. Over-marinating can make the tuna mushy.
A dry rub can also add a wonderful flavor. Combine salt, black pepper, garlic powder, onion powder, smoked paprika, and a pinch of cayenne pepper. Rub the mixture evenly over the tuna steaks.
Preparing the Griddle
A properly prepared griddle is essential for achieving perfectly seared tuna steaks.
Cleaning and Seasoning the Griddle
Before you start cooking, make sure your griddle is clean. Scrape off any food residue with a metal spatula. Wipe the griddle down with a damp cloth.
If you have a cast-iron griddle, it’s important to keep it seasoned. After cleaning, lightly coat the griddle with a high-heat oil, such as canola or avocado oil. Heat the griddle until the oil starts to smoke, then let it cool. Repeat this process a few times to build up a good seasoning.
Heating the Griddle to the Right Temperature
The griddle needs to be hot before you add the tuna steaks. Aim for a medium-high heat. You should be able to hold your hand a few inches above the griddle for only a few seconds.
A properly heated griddle will ensure a good sear and prevent the tuna from sticking.
Grilling the Tuna Steaks
With the tuna prepped and the griddle hot, you’re ready to start grilling.
Adding Oil to the Griddle
Even if your griddle is well-seasoned, it’s a good idea to add a little oil before you add the tuna steaks. This will help prevent sticking and ensure a good sear. Use a high-heat oil, such as canola or avocado oil. Spread the oil evenly over the griddle surface.
Placing the Tuna Steaks on the Griddle
Carefully place the tuna steaks on the hot griddle. Make sure there is enough space between the steaks to allow for even cooking. Avoid overcrowding the griddle, as this can lower the temperature and prevent a good sear.
Searing the Tuna
The key to grilling tuna steaks is to sear them quickly on the outside while keeping the inside rare or medium-rare. Sear the tuna for 2-3 minutes per side, depending on the thickness of the steaks and your desired level of doneness. Do not overcook.
Use a spatula to carefully flip the tuna steaks. Avoid moving them around too much, as this can prevent a good sear.
Checking for Doneness
Use a meat thermometer to check the internal temperature of the tuna. For rare, aim for 125-130°F (52-54°C). For medium-rare, aim for 130-135°F (54-57°C). For medium, aim for 135-140°F (57-60°C).
You can also use the poke test to check for doneness. Gently press on the center of the steak with your finger. Rare tuna will feel soft, medium-rare will feel slightly firmer, and medium will feel firm.
Resting and Serving
Allowing the tuna steaks to rest after grilling is crucial for retaining their moisture and flavor.
Resting the Tuna
Remove the tuna steaks from the griddle and place them on a cutting board. Tent them loosely with foil and let them rest for 5-10 minutes. This allows the juices to redistribute throughout the steak, resulting in a more tender and flavorful result.
Slicing and Serving Suggestions
After resting, slice the tuna steaks against the grain. This will make them easier to chew.
Serve the tuna steaks immediately. They are delicious on their own or with a variety of accompaniments. Consider serving them with a side of grilled vegetables, such as asparagus, zucchini, or bell peppers. A simple salad with a light vinaigrette is also a great choice.
For a more elaborate meal, serve the tuna steaks over rice or noodles with a flavorful sauce. Teriyaki sauce, ponzu sauce, or a wasabi aioli are all excellent options.
Consider these serving suggestions:
- Seared Tuna Salad: Top a bed of mixed greens with sliced seared tuna, avocado, cucumber, and a sesame ginger dressing.
- Tuna Steak Tacos: Serve sliced seared tuna in warm tortillas with slaw, avocado crema, and a squeeze of lime.
- Tuna Poke Bowl: Combine diced seared tuna with rice, avocado, seaweed salad, edamame, and a spicy mayo.
Griddle Cleaning and Maintenance
Proper cleaning and maintenance will ensure your griddle lasts for years to come.
Cleaning After Each Use
After each use, scrape off any food residue with a metal spatula. Wipe the griddle down with a damp cloth.
If there are any stubborn spots, you can use a scraper or a grill brush to remove them.
Seasoning After Cleaning
If you have a cast-iron griddle, it’s important to re-season it after cleaning. Lightly coat the griddle with a high-heat oil and heat it until the oil starts to smoke. Let it cool, and then repeat this process a few times.
Preventing Rust
To prevent rust, make sure your griddle is completely dry before storing it. You can also apply a thin coat of oil to the surface.
Store the griddle in a dry place. If you live in a humid environment, consider storing it in an airtight container with a desiccant pack.
By following these tips, you can ensure your griddle stays in good condition for years to come.
Troubleshooting Common Issues
Even with the best preparation, you may encounter some common issues when grilling tuna on a griddle. Here are some tips for troubleshooting:
- Tuna is sticking to the griddle: Make sure the griddle is hot enough and well-oiled. Avoid moving the tuna around too much while it’s searing.
- Tuna is cooking unevenly: Ensure the tuna steaks are of a uniform thickness. Use a meat thermometer to check the internal temperature of different parts of the steak.
- Tuna is too dry: Avoid overcooking the tuna. Use a meat thermometer to monitor the internal temperature. Marinating the tuna can also help to keep it moist.
- Tuna is not searing properly: Make sure the griddle is hot enough. Pat the tuna steaks dry before adding them to the griddle. Avoid overcrowding the griddle.
By addressing these common issues, you can achieve perfectly grilled tuna steaks every time.
Grilling tuna steaks on a griddle is a simple and rewarding way to enjoy this delicious fish. By following these tips and techniques, you can create a restaurant-quality meal in the comfort of your own home. Enjoy!

What type of tuna steak is best for grilling on a griddle?
For grilling on a griddle, look for tuna steaks that are at least one inch thick. This thickness helps prevent them from drying out too quickly and allows for a nice sear on the outside while keeping the inside tender. Opt for varieties like ahi tuna (yellowfin) or bigeye tuna, as they are known for their robust flavor and firm texture, which holds up well to the high heat of a griddle.
Also, ensure the tuna steaks are fresh and of high quality. The color should be a vibrant red or pink, with no browning or dullness. A slight sheen indicates freshness. Avoid steaks that appear waterlogged or have a fishy odor, as these are signs of spoilage. Fresh, thick tuna steaks are key to achieving the best results when grilling on a griddle.
How do I properly prepare tuna steaks before grilling?
Before grilling, gently pat the tuna steaks dry with paper towels. Removing excess moisture helps achieve a better sear and prevents the steaks from steaming instead of grilling. Next, lightly brush both sides of the tuna steaks with olive oil or another high-heat cooking oil. This will help prevent sticking to the griddle and promote even cooking.
Season the tuna steaks generously with salt and freshly ground black pepper. You can also add other seasonings like garlic powder, onion powder, paprika, or your favorite spice blend. Consider a marinade if you want to infuse additional flavor, but be mindful that marinades can sometimes cause the tuna to cook faster and potentially dry out. Marinate for no more than 30 minutes and pat dry before placing on the griddle.
What is the ideal griddle temperature for grilling tuna steaks?
The ideal griddle temperature for grilling tuna steaks is medium-high heat, typically between 400°F and 450°F (200°C and 230°C). This high heat allows you to quickly sear the outside of the tuna while keeping the inside rare to medium-rare, which is how tuna is best enjoyed. Using a lower temperature will result in a longer cooking time and potentially dry out the tuna.
Ensure the griddle is properly preheated before placing the tuna steaks on it. A hot griddle is essential for achieving a good sear and preventing the tuna from sticking. You can test the temperature by flicking a drop of water onto the surface; if it sizzles and evaporates quickly, the griddle is ready. Adjust the heat as needed to maintain a consistent temperature throughout the cooking process.
How long should I grill tuna steaks on a griddle?
The grilling time for tuna steaks on a griddle depends on their thickness and your desired level of doneness. For 1-inch thick steaks, a good starting point is about 2-3 minutes per side for medium-rare. If you prefer a rarer center, reduce the cooking time slightly. For medium doneness, cook for an additional minute or two per side.
Use a spatula to gently lift a corner of the tuna steak to check for doneness. The outside should be nicely seared, and the inside should still be pink or red, depending on your preference. Avoid overcooking the tuna, as it can become dry and tough. Remember, tuna is best enjoyed when it’s cooked rare to medium-rare.
How do I prevent tuna steaks from sticking to the griddle?
Preventing tuna steaks from sticking to the griddle starts with proper preparation. Make sure the griddle is clean and properly preheated before adding any oil or food. A clean, hot surface is less likely to cause sticking. Secondly, lightly brush both sides of the tuna steaks with oil before placing them on the griddle. This creates a barrier between the tuna and the surface.
Avoid moving the tuna steaks around on the griddle too much. Allow them to sear undisturbed for the recommended cooking time on each side. Once a good sear has formed, the tuna should release easily from the griddle. If you try to flip it too early, it may stick and tear. Using a thin, flexible spatula can also help to gently release the tuna steaks without damaging them.
What are some recommended toppings or sauces to serve with grilled tuna steaks?
Grilled tuna steaks are incredibly versatile and pair well with a variety of toppings and sauces. A classic pairing is a simple squeeze of fresh lemon juice and a sprinkle of sea salt. You can also create a flavorful Asian-inspired glaze using soy sauce, honey, ginger, and garlic. This adds a touch of sweetness and umami to the dish. Another great option is a creamy avocado salsa, which provides a cool and refreshing contrast to the seared tuna.
For a more sophisticated flavor profile, consider a balsamic glaze reduction or a Dijon mustard vinaigrette. Fresh herbs like cilantro, parsley, or chives can also be used to add brightness and enhance the overall flavor. Experiment with different combinations to find your favorite pairing, and don’t be afraid to get creative with your toppings and sauces.
How do I store leftover grilled tuna steaks?
To properly store leftover grilled tuna steaks, allow them to cool completely to room temperature before storing. Once cooled, wrap them tightly in plastic wrap or place them in an airtight container. This will help prevent them from drying out and absorbing odors from the refrigerator.
Store the wrapped tuna steaks in the refrigerator for up to 2 days. When reheating, it’s best to gently warm them in a skillet over low heat or in a microwave on a low power setting. Be careful not to overcook them, as they can easily become dry. Leftover grilled tuna can also be used in salads, sandwiches, or wraps for a flavorful and convenient meal.
